TURBOTEST 500B User’s Guide
Feature Overview
High-speed transmission systems employ laser sources with narrow bandwidths, which are sensitive to
back-reflections caused by components, splices, and connectors. If too much light is reflected back to
the laser transmitter, the modulation characteristics and spectrum of the laser may change. This change
will degrade the systems performance. For efficient operation of the laser transmitter, it is necessary
to test for optical return loss caused by back-reflections.
Note:
Most manufacturers of fiber optic transmission systems specify the maximum allowable return
loss for error free operation.
The TURBOTEST 500B offers the latest technology in a single fiber bi-directional loss and return loss
testing that provides the exchange of loss data and references between units. The instrument performs
three fiber optic measurements: Optical Power (OPM), Optical Return Loss (ORL), and Optical Loss
(OLTS) measurements. In automatic TURBO mode, the instrument performs both Optical Return Loss
(ORL) and Optical Loss (OLTS) measurements.
The TURBOTEST 500B can store up to 920 records in any combination of its four operating modes and
if any configuration other than TRIPLE wavelength is selected. If the configuration is TRIPLE wavelength,
the TURBOTEST 500B can store up to 460 records. Stored test results can be transferred to a PC for
a complete report generation. For a complete description of the PC executable software, refer to the
User’s Guide supplied with the software.
An optional dedicated digital TALK option is available for full time/full duplex communication between
test operators while testing other fibers in a bundle.
The TURBOTEST 500B is powered by the internal rechargeable Lithium-Ion battery pack or external
AC power adapter.
Recommended Accessories
You will need fiber optic test jumpers to connect the TURBOTEST 500B to the fiber under test. Test
jumpers must have the same core and cladding size as the fiber under test. The connector at one end
of the test jumper must mate with the appropriate optical port on the TURBOTEST 500B. The connector
on the other end must mate with the fiber optic link under test. Test jumpers with a variety of lengths
and connector styles are available from Noyes.
Optical ports and connector end faces must be kept free from dirt or other contaminates to ensure
accurate measurements and operation.
For cleaning connector end faces on the TURBOTEST 500B Voice and Test Ports, test jumpers, and in
fiber frames or adapters, Noyes recommends using our exclusive FCC2 non-hazardous cleaning fluid
and CCT molded cleaning tips.
The FCC2 fluid is a non-flammable, environmentally safe, residue free solvent engineered to clean fiber
connector end-faces.
The CCT molded cleaning tips introduce a new fiber connector end face cleaning technology. Rather than
